Vaught attended Western Kentucky University, starting in 2012, and was named to the dean’s list in 2015.

In addition to nursing, Vaught appears to own a company that sells hunting clothing — Horny Outdoors Apparel — with her husband, Ed.

Vaught also has public Twitter account which she has not updated since 2013. Of the few tweets she has sent, many are related to gun rights, self-defense and the Second Amendment, including one photo where she holds a shotgun while wearing what appears to be red nursing scrubs.

Vaught was indicted by a grand jury on Friday for charges of reckless homicide and impaired adult abuse. Grand jury proceedings are secret and sealed, so details of these criminal allegations against her not entirely known.

Vaught appears to have bailed out of jail since her arrest. She does not currently have a lawyer listed in her criminal case. She is scheduled to appear in court for an arraignment on Feb. 20.

Versed vs. vecuronium

The medication error occurred on Dec. 26, 2017, while Murphey was being treated at Vanderbilt for a subdural hematoma that was causing a headache and loss of vision. Despite these symptoms, she was alert, awake and in improving condition, according to the federal investigation report from the Centers for Medicare and Medicaid Services.

Murphey was taken to Vanderbilt’s radiology department to receive a full body scan, which involves lying inside a large tube-like machine. Because the she was claustrophobic, a doctor prescribed a dose of Versed, which is a standard anti-anxiety medication.

A nurse then went to fill this prescription from one of the hospital’s electronic prescribing cabinets, which allow staff to search for medicines by name through a computer system. The nurse could not find the Versed, so she triggered an “override” feature that unlocks more powerful medications, according to the investigation report.

The nurse then typed the first two letters in the drug’s name – “VE” – into the cabinet computer and selected the first medicine suggested by the machine, not realizing it was vecuronium, not Versed.

Murphey lost consciousness and never recovered. She died about 1 a.m. the next day after family members agreed to disconnect her from a breathing machine.

“They said she was not going to get no better,” said Charlene Murpehy's husband, Sam, on Monday night. “So I did it – I had to do it – I couldn’t keep her like that.”

Vanderbilt officials have said the hospital acted swiftly after the death, including explaining the mistake to the family and taking "personnel actions." The hospital also cooperated with the criminal investigation into Vaught, a spokesman said.
